Saying the wrong things
Sometimes I say the wrong things in class and I would be very bothered by it after the lesson, wondering if I had offended any of my students. And I would lay awake at night, tossing and turning in bed, and worrying that my students would henceforth have a very bad impression of me, and bitch about me to all and sundry and I would have to work doubly hard from then on to regain my standing in class.
Maybe I shouldn't be so fanatically anxious about such slips of the tongue. To err is human, after all. Maybe most of my students aren't even listening when I talk (ha ha!).
Maybe I should just state here that if any student has ever felt offended by anything I have said, that you should just approach me and tell me. Sometimes I come across as being very blunt, or demanding, or impatient or even arrogant. Sometimes I may even be wrong. (In fact, no teacher is ever right all the time.) But I won't realise it, until I get some kind of feedback from you. I promise I won't take it out on your essay marks! :)
